Nie mogę się dostać do MySQL

Nie mogę się dostać do MySQL - instalacja

MaestroS - 05-01-2009 17:31
Problem jest w poleceniu (mysql -u root). Nie mogę się dostać do MySQL ani przez konsolę, ani przez phpMyAdmin. Co jest?

grzesiek - 05-01-2009 17:59
Nie :!: Problem jest w tym
mysqladmin -u root password 'password'

To i tak nic nie daje: mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)' Tak jest nawet jak przeinstaluje wszystkie pakiety. Nie wiem, co się dzieje.

A jak wpiszę: mysqld ks23098:/# mysqld
InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
090105 18:25:26 InnoDB: Retrying to lock the first data file
InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files. Na poprzednim serwerze dedykowanym nic takiego nie miało miejsca. Akurat na moim MySQL nie chce w ogóle działać. Skorzystałem już dla ,,cukrowanej'' pewności z 3 opisów i nic.

Ech musisz coś źle wpisywać. Kolejności jest taka: instalujesz, ustawiasz hasło dla roota.
A ten: co pokazywałeś to tak jak tam jest napisane - już jest uruchomiony.

MaestroS - 05-01-2009 19:32
grzesiek, jeżeli spojrzysz wyżej, to możesz zauważyć, że pomimo tego, że mysqld już działa, to:

mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)' I tu jest pies pogrzebany.

grzesiek - 05-01-2009 19:54
A to informuje, iż logowałeś się na root@localhot ale nie podałeś parametru -p (hasło)

MaestroS - 05-01-2009 20:02
Ale ja nie wiem jakie mam hasło! Puste nie działa, a jeszcze go nie ustawiałem. Ten błąd pojawia się za każdym razem. Przy każdej próbie logowania, czy zmiany hasła.

grzesiek - 05-01-2009 20:10
Ten cały komunikat to jedno i to samo. Pierwsza linia mówi, że nie udało się logowanie, a druga to zawartość błędu zwróconego przez funkcję logowania, czyli dlaczego logowanie się nie udało.

Więc tak instalujesz MySQL wpisujesz: mysqladmin -u root password haslo a potem: mysql -u root -p
(prosi o hasło)
hasło i otrzymujesz komunikat? mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)' :evil:

MaestroS - 05-01-2009 20:29
Specjalnie dla Ciebie: ks23098:~# mysqladmin -u root password przyklad
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

ks23098:~# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
ks23098:~# Czy to nie wynikało z moich postów?

grzesiek - 05-01-2009 20:41
A pokaż konfig i w między czasie spróbuj bez podawania hasła np.
mysqladmin -u root
mysqladmin -u root password
mysqladmin -u root -p Ale przedewszystkiem sprawdz czy mysql dziła
ps -A | grep mysql Nic nie zmieniałeś w localhost=127.0.0.1?

dsue - 05-01-2009 20:45
Napisz co ci daje komenda: ps ax|grep mysql

i nie uruchamiałbym mysqla przez mysqld tylko /etc/init.d/mysql start (albo restart)

Pozdrawiam

Pokaż wynik polecenie
netstat -ltnp | grep :3306 oraz
ls /var/run/mysqld/ | grep mysqld.sock oraz
cat /etc/hosts | grep localhost Sprawdz czy MySQL uruchomi się gdy zakomentujesz opcję bind-address = 127.0.0.1 Z tego co widzę to masz logi wyłączone, odkomentuj opcję #log = /var/log/mysql/mysql.log spróbuj ustawić hasło roota i pokaż logi.

Na razie to wszystko co mi przychodzi do głowy. Zostaje jeszcze zrestartować kompa (ale to już na pewno robiłeś), a nawet zostawić to do jutra, może jutro zacznie działać ;-) kto wie.

Nie wiem co jest grane. Ale po głowie chodzi mi coś takiego, że może paczka jest walnięta albo się źle ściągneła. Czy przed ponownym zainstalowaniem wyczyściłeś cacha apt? Bo on przechowuje paczki już raz pobrane. może Wyczyść te jego cacha i jeszcze raz spróbuj - jak masz jeszcze siły.
